Welcome! Let’s get you building.

What if you could get a perfect first layer the first time, and every time, with no need to calibrate?

“Zero calibration required” isn’t a phrase often thrown around in the DIY and Maker communities, but that’s exactly what this sensor aims to achieve. It takes the guesswork out of bed leveling, z-height, and probe offsets, because with the Pyr0-Piezo Z-Probe, your nozzle itself is the sensor. 

What’s the single biggest challenge to overcome with 3D Printing?

In my experience, it’s the first layer. If you can get a perfect first layer to stick and get that perfectly smooth, glossy upper surface, then it’s a fairly good bet that the rest of your print will go down perfectly.

It’s for this reason there are so many different Z-Probes available for 3D Printers, all in the pursuit of getting that first layer just so. But most of these sensors have at least one problem in common: Calibration and Drift

How it Works

Piezoelectric sensors use a piezo element (usually a disk like the ones found in musical pickups) mounted on the printer in such a way that the mechanical force of touching the bed with the nozzle causes the disk to flex, which generates a signal. That signal gets filtered and conditioned and is sent to the Printer’s controller as if it was any other endstop.

This style of sensor usually has one drawback, however, which is that it’s electrical filtering circuit needs to be calibrated to a specific state that changes depending on the printer it’s installed on. Conditions like temperature, or differing input voltage can cause a piezo sensor’s calibration to get skewed.

The Pyr0-Piezo, on the other hand, can account for these variances. It has an onboard microcontroller (a tiny CPU) that constantly monitors the circuit and makes on-the-fly adjustments to ensure the filtration circuit remains stable and ready to probe at all times. Hence, the calibration of this sensor, while still necessary, is completely automated.
